Problems solved by technology

Cellular telephones provide mobile telephone service that follows a user, but pager and cell phone services are expensive and rely on sufficiently-charged batteries to power the mobile equipment.
Mobile area coverage is uncertain and call quality is typically lower than for hard-wired communication systems.

Embodiment Construction

[0016]The present invention is believed to be applicable to various types of communication systems, including telephony systems, and has been found particularly suited to broadband data network telephony systems, including systems which route the communications via an Internet protocol (IP) network. While the present invention is not necessarily limited to such telephony systems, various aspects of the invention may be appreciated through a discussion of various examples using this context.

[0017]Conventionally, a telephony system caller desiring to call “someone” actually designates to the telephony system, by dialing a telephone number, an identifier for a telephony system circuit or channel. Typically, one or more communication devices are hard-wired to the telephony system or channel. Where more than one communication device is connected to a particular circuit, the communication devices operate together in parallel. Conventionally, communication equipment, rather than people, ar...

Abstract

The present invention is directed to a method and system for routing communications. A plurality of communication devices are coupled to a communications network. Each communication device has a device identifier. A user-programmable database associates each of a plurality of user identifiers with a device identifier. A call-routing switch arrangement is coupled to the communication network through a portal communication device having a portal identifier. A user designates a destination user identifier when making a communication. The call-routing switches the call, directing the call to a destination device identifier responsive to the user-programmable database association between the destination user identifier and a device identifier. According to the present invention, communications are directed to users and are routed to associated equipment, a user identifier serving as a virtual extension number. Users remotely program the database to direct their calls to communication devices at various geographic, voice mail and e-mail destinations.
